How To Specify Windowsize for pitch~ or fiddle~?


    Mar 08 2010 | 2:25 am
    Hi, I am looking to be able to vary the windowsize for either pitch~ or fiddle~. In the documentation, it does not say what message (if there is one) to send either object to change its FFT windowsize. Similarly, in pfft~, there does not seem to be a message to be able to change windowsize. Is this possible for an FFT? I'd like to have an FFT windowsize that matches the size of a grain, for pitch analysis of a single grain.

      Hi
      Check the pitch~ help patch.
      No message - use the arguments in object.
      Args are - def.
      Buffer size = 1024
      Hop size = 512
      FFT size = 1024
      Window type = Blackman 70
      Initial delay = 0
      # of pitches = 1
      # of peaks to find = 20
      # peaks to output = 0
      Hope that helps.

      but in that case the grainsize needs to always be the same. i'd like to be able to dynamically change the FFT window size.

      I don't think you can do this dynamically after instantiation. You might have to use multiple instances and route to the one you need.

      I am afraid you would need to code it yourself either in Java or in c...
      But if you just send the sound of a grain to fiddle~, what is the result? It might just be good enough...
